How to Enable MFA on Microsoft 365 for Better Security

Cybersecurity threats are on the rise, and protecting your Microsoft 365 environment has never been more critical. A simple yet powerful way to boost your defenses is to enable MFA on Microsoft 365. Multi-factor authentication (MFA) provides an extra layer of security by requiring users to verify their identity with something more than just a password. Why is this so important?

Consider this scenario: an employee’s password is compromised through a phishing attack. Without MFA, that’s a direct door into your company’s sensitive data. With MFA enabled, the attacker would also need access to a second factor, like a mobile authentication code or biometric confirmation, greatly reducing the risks.

Another instance where MFA proves invaluable is with remote work. Employees logging in from various devices and locations pose a greater security risk, but MFA ensures those accessing company resources are who they say they are. To dive deeper into how multi-factor authentication works and the security advantages it offers, check out Microsoft’s guide on MFA basics and setup, or explore their recommendations for protecting your accounts. Getting started with MFA might just be the smartest move you make for your organization’s security today.

By enabling MFA, you can reduce the chances of a hack by up to 99.9%! In this post, I’ll walk you through how to set it up for your Microsoft 365 account.

Why Enable MFA on Microsoft 365 is Important?

Think about your email account. If someone hacks into it, they could cause a lot of damage. They could send phishing emails to your contacts, steal money by altering payment details, or even sit quietly in your inbox waiting for the perfect moment to strike.

Multi-Factor Authentication adds an extra layer of protection. With MFA, even if someone has your password, they still can’t access your account without an additional verification step.

Understanding Security Defaults in Microsoft 365

By default, Microsoft 365 tenants have Security Defaults enabled. This feature automatically enforces baseline security measures, including:

Mandatory MFA for all users.
Blocking legacy authentication protocols.

Security Defaults aim to protect organizations from common attacks without requiring advanced configurations. However, they may not suit organizations needing tailored security settings.

In these cases, admins can disable Security Defaults and implement other MFA options, such as per-user MFA or Conditional Access policies (the latter is more advanced and will be covered separately).
